Saracens return to top of Premiership with Harlequins win in front of record crowd at Wembley

Saracens director of rugby Mark McCall questioned why a dangerous tackle on David Strettle was not referred to the television match official in the Aviva Premiership leaders' 39-17 victory over Harlequins.

Strettle was carried off on a stretcher in the sixth minute after a swinging arm from number eight Maurie Fa'asavalu knocked him out amid a physical start to the Wembley showdown.

Referee Tim Wigglesworth failed to consult the TMO even though Strettle received treatment for several minutes.

Replays of the incident were damming, but McCall refused to condemn Fa'asavalu.

"I didn't see the angle everyone is talking about, so I can't comment on it," McCall said.

"It would be foolish for me to say anything. David is OK. He's pretty shaken up but he's OK.

"The Richard Wigglesworth penalty which the referee came back for was something out of nothing compared to what happened to David.

"There is a system that can be used by the officials in this situation. Clearly it wasn't used as well as it could have been.

"In all matches a couple of things go on that probably shouldn't."

The tackle is sure to interest the citing officer, but Quins director of rugby Conor O'Shea backed Fa'asavalu. He said: "There should be nothing on that. I've seen it."
